Intimate scenes with Portman were hard: Mila Kunis

Actress Mila Kunis had a hard time filming an intimate scene with Natalie Portman -- but said similar scenes with Justin Timberlake were enjoyable.

Kunis, who stars in this week's new film, "Black Swan", told Parade magazine that she agreed to film the erotic sequence because she felt that it was "important" to the journey that her character goes through over the course of the movie.

"We knew it was going to attract attention. We were just hoping that people would walk away after seeing the movie not just isolating in their memory that scene when we have sex," she said.

The "That '70s Show" star added: "I think it's important to the story. It wasn't done for shock value, but we weren't looking forward to it."

She said what made it worse was that Portman is a close friend.

"I don't think we were laughing between takes. I think we were like, 'Let's just get this over with'. It's uncomfortable doing a sex scene. It's just bizarre. Luckily, we were friends, so we were able to get through it."

But sex scenes with Justin Timberlake were enjoyable, she said. "Justin and I have quite a few unclothed moments. But he made it easy for me by kidding around and keeping me laughing," femalefirst.co.uk quoted Kunis as saying.

The two will be seen together on the big screen in "Friends With Benefits", which also stars Emma Stone and Woody Harrelson.

"Justin Timberlake and I play friends who are in a relationship where they try to have casual sex without any emotional attachment."

Kunis had to shoot several sex scenes in the past as well and she claims her father walked out of the sets during the filming.

"I feel sorry for my dad though. If I'm not mistaken, he walked out during the sex scene in 'Black Swan'," she said.
